Definitions
- the invention relates to a conveyor unit for conveying Fuel from a storage tank, especially for Internal combustion engines, which in the preamble of claim 1 defined genus.
- tank installation unit Conveyor unit of this type (DE 44 44 854 A1) is the electric drive motor of the feed pump with its cylindrical outer jacket fits snugly in the central chamber of the Filter pot added and is supported on the front on the one hand on a stop collar on the drive motor separated pump housing and on the other hand on elastic Support elements on the underside of the filter cover.
- the pump outlet opens into the central chamber, from where the Intake fuel via a check valve provided inlet channel flows into the annular chamber, there the Main filter flows through and via the drain channel into the Delivery line arrives.
- the drain connector on the filter cover is over a flexible corrugated pipe with one in a tank flange arranged connection piece for the delivery line connected.
- the tank flange closes those in the storage tank provided opening for installing the conveyor unit.
- the filter bowl is axial and radial in the storage tank fixed, why between the filter bowl and elastic coupling elements on the inside wall of the storage tank and a safeguard against axial displacement is provided are. Because of the elastic coupling of the filter bowl the storage tank it is also imperative that the Connection line between the drain connector on Filter cover and the connecting piece on the tank flange is elastic.
- a well-known Conveyor unit (DE 37 30 930 A1) is the one Suction nozzle in a suction pump projecting into a suction space laterally in a longitudinally C-shaped housing used and axially between the two housing legs and supported radially.
- suction space in the housing for fuel flowing back from the internal combustion engine provided in the one returning the fuel Return line opens.
- the suction space is above a first one Suction chamber opening with the inside of the storage tank and over a second suction space opening with the storage space in Connection.
- Both suction chamber openings are in each other opposite wall sections of the suction chamber introduced and are arranged by a valve member arranged in the suction chamber alternately released and locked.
- the valve member is operated by a float and closes at filled suction chamber the second suction chamber opening and gives the first suction chamber opening free.
- a conveyor unit for Pumping fuel from a storage tank known to the has a filter bowl with a central chamber which of is enclosed in an annular chamber.
- the ring chamber is on one of its end faces closed by a filter cover, with an inlet channel and a on this filter cover Drain channel to or from the annular chamber are trained.
- In the central chamber is an electrical one Fuel feed pump arranged, the inlet via a Suction nozzle protrudes into a suction space.
- the diameter of the central chamber matches that of the Conveyor unit coincides, in addition, the suction nozzle recorded directly in the filter bowl.
- the filter bowl is supported via a spring on the bottom of the storage container. This is relatively complex and can with respect to the transfer of Not all operating noises Satisfy use cases.
- the object underlying the invention is propose a delivery unit in which the feed pump is decoupled from the filter bowl for noise reasons, so that this can be fixed rigidly in the storage tank.
- This task is of an object with the features of claim 1 solved.
- the inside diameter is Central chamber larger than the outer diameter of the housing the feed pump. Possible contact points of this feed pump with the filter bowl only exist in the area of Suction and pressure port. In order to have a To achieve decoupling are between these sockets and the filter bowl sleeves made of elastic material.
- the one with the inlet port of the filter bowl is coupled to the pressure port also formed on a push-on cap of the filter cover, that overlaps the pressure port.
- the conveyor unit according to the invention with the features of Claim 1 therefore has the advantage that the housing Electromotive feed pump decoupled from the filter bowl is.
- the feed pump is on both ends of your also housing the electric motor axially and radially mounted elastically and can thus their swinging movement when Operation is not transferred to the filter bowl, so that the latter can be rigidly attached in the storage tank.
- the flexible corrugated pipe between filter cover and tank flange can thus eliminated, so that the tightness associated with it Strength problems disappear.
- the assembly of the Conveyor unit is significantly simplified because the Delivery pump only with its suction nozzle through the Insert the opening in the bottom of the filter bowl and the filter bowl must be closed with the filter cover, after each on the intake and discharge ports elastic sleeve has been pushed on.
- the Filter cover one axially protruding on its underside annular collar with one of the clear width of the Ring chamber corresponding radial width, the front one in the annular chamber with the interposition Ring seal to the inner and outer ring chamber wall used and with the filter bowl, preferably through Flanging the inner and outer ring wall, firmly connected is.
- the channels formed in the filter cover for the Fuel inlet and outlet open into the annular chamber covering closing surface of the closing collar.
- the filter cover in Area of the central chamber is open or has at least one access opening to this and one cylindrical wall area on that of the filter bowl facing end of the filter cover is formed and a circular connection opening for one Insertion opening for the conveyor unit in the storage tank sealing tank flange bounded.
- the conveyor assembly according to the invention with the characterizing features of claim 11 has the Advantage that through the direct connection of the Pump outlet of the feed pump via its pressure port the inlet channel to the annular chamber formed in the filter cover in the filter bowl and the introduction of the fuel return line directly into the filter bowl Central chamber in the filter bowl is always filled with fuel is, so that when the fuel level in the suction chamber arranged below the filter bowl Open the locking member of the suction chamber from the central chamber is refilled with fuel and the feed pump over their intake manifold continues to deliver fuel undisturbed.
- Such a temporary drop in the fuel level in the suction chamber occurs at a low level in the storage tank when the vehicle turns sideways as a result of cornering inclines.
- a second Embodiment proposed the locking member with a to provide hydraulically controllable pressing device.
- This Pressure device is only in the idle state Delivery pump effective, its function is in delivery operation due to a hydraulic pressure generated by the feed pump canceled. This measure is even under Adequate supply of the extreme conditions Feed pump with fuel ensured.
